For Sale: 53cm Bob Jackson Vigorelli, Phil Wood, Velocity, Sugino

Nope don't think so I've been experimenting getting the right size for me and think smaller the better as I'm only 5'8/9 ish

I quote "However i need to stop kidding myself its the right size, i usually ride a 56"

From your other thread.

Pick a size and stick to it because unless you're 15, you're not going to change much size wise.
